Explanation:

Do now Questions:

1. Difference between a line and a line segment

A line is a straight path that extends infinitely in both directions, with no endpoints. A line segment is a part of a line that has two distinct endpoints and a definite length.

A line segment has two endpoints and a definite length. A ray has one endpoint and extends infinitely in one direction from that endpoint.

Step 1: Identify the figure type

The figure has markings indicating that it is a parallelogram (opposite sides are marked as equal and parallel).

Step 2: Recall the property of a parallelogram

In a parallelogram, opposite sides are equal. So, \(BC\) and \(AD\) are opposite sides of the parallelogram.

Step 3: Substitute the given value

We know that \(AD = 5\). Since \(BC=AD\) (from the property of the parallelogram), then \(BC = 5\).

Answer:

A line extends infinitely in both directions (no endpoints); a line segment has two endpoints and a fixed length.

2. Difference between a line segment and a ray
